The epoxy infusion workshop in Caen, from the Class40 Legallais to decks for Multiplast
Foundation
Grand Largue Composites was founded in 2007 on the Calix basin in Caen (Mondeville, Calvados) by Xavier Gosselin and Jean-François Lilti, following the Avocet 50 catamaran project. Today, Xavier Gosselin runs a facility with around half a dozen permanent staff, supplemented by specialists brought in for projects.
Technical specialty
The workshop specializes in epoxy infusion for small to medium-sized parts, where most of the marine market still uses polyester. It has out-of-autoclave (OOA) capabilities and self-heating molds up to 200 °C, opening doors to industrial and aeronautical markets.
The marine sector accounts for about 65% of activity, with the remainder split between aeronautics and industry.
Caen ecosystem
The yard collaborates closely with neighboring structures on the Caen basin — V1D2, Shoreteam Yard, Normandy Yacht Service — on optimizations and refits of boats coming out of the workshop.
